A continuous hot-dip plating machine (1) includes: a sink roll (6) provided in a plating bath (3) and configured to upwardly change a transfer direction of the steel strip (2); a first support roll (7) provided in the plating bath (3) and located above the sink roll (3), the first support roll (7) being in contact with a first surface of the steel strip (2) in contact with the sink roll (6); and a second support roll (8) provided in the plating bath (3) and located above the first support roll (7), the second support roll (8) being in contact with a second surface of the steel strip (2) opposite the first surface. A diameter (D1) of the first support roll (7), a diameter (D2) of the second support roll (8), and a vertical distance (L) between a rotation axis of the first support roll (7) and a rotation axis of the second support roll (8) satisfy specific conditions.
